The destruction of the Euro is not so bad Marshall , why do you want this Trojan horse to remain for the night inside former nation states Castle Gates ?
Countries can Print their own local currencies to restore domestic demand and reduce the waste inherent in the extreme interconnectivity of euro trade and especially capital interactions just as Ireland did a little bit during the last EMU crisis of 1992/93.
Greece ,Ireland Spain etc would be fine if they just reduced the export of hard currency which is destroying their internal economies yet enriching Arab sheiks and German BMW merchants.
